Abstract
The mechanism for opening and closing an operating cover of a printer having a discharge guide that remains in the same posture while moving in conjunction with opening and closing the operating cover prevents the gap between the discharge guide and the cover case of the operating cover from widening when the operating cover opens and closes. In a roll paper printer 1, the top end part 32a of the cover case 32 of an operating cover 3 is pivotably attached on the side of the discharge guide 5, which remains in the same posture while moving in conjunction with the cover 3 opening and closing. So that the cover case 32 does not separate from the cover frame 31 when the cover 3 opens and closes, a torsion spring 37 constantly urges the cover case 32 to open and close in unison with the cover frame 31 through an intervening connector arm 34. When the cover 3 opens and closes, a large gap is not formed between the top end part 32a of the cover case 32 and the discharge guide 5, and this gap does not increase in conjunction with the cover 3 opening and closing.

The record-paper 12a that roller paper 12 from be housed in roller paper resettlement section 11 is pulled out upward such as Fig. 2, shown in Figure 3, be erected on the tensioning guide 20 after the bending forwards, from passing through between feeding-in roll 21 and the air roll 22 between ink gun 14 and the hold-down plate surface 19, be configured to be pulled out to outside state from record-paper outlet 4.
Under this state, when balladeur train 15 was moved back and forth, 14 pairs of ink guns that utilize to carry on balladeur train 15 were extracted out and the part surface that is positioned at the record-paper 12a of print position prints from roller paper 12.After a series of line printings to the width of record-paper 12a finish, send record-paper 12a with prescribed distance, carry out the printing of next line.Like this, record-paper 12a utilizes ink gun 14 to implement to print when intermittently sending with prescribed distance.Dispose the record-paper shearing device (not shown) that the record-paper shearing device for example presss from both sides formula at the record-paper outlet 4 of discharging the record-paper 12a after printing.Utilize the record-paper 12a of record-paper shearing device broad ways cut-out between them.The record scraps of paper after the cut-out fall to the position of regulation under the deadweight effect along row's paper guide 5 after discharging from record-paper outlet 4.
(open-close lid structure)
Then, with reference to Fig. 2, Fig. 3 and Fig. 4 the open-close lid structure that is used to open and close open-close lid 3 is described.Open-close lid 3 by the open-close lid framework 31 of sheet metal system and the plastic open-close lid housing 32 of state that is configured to cover the front of this open-close lid framework 31 constitute.The open-close lid 3 of this structure is state to be opened/closed by parallel linkage 7 supportings of 4 joints.Parallel linkage 7 by the rear side parallel rod 72 of the front side parallel rod 71 of pair of right and left, pair of right and left, and the pressing plate framework 18 that connects the upper end of above-mentioned member constitute.About front side parallel rod 71 between set up header board 31a along the printer width.The back side that the front butt of this header board 31a open-close lid housing 32.Thereby in this example, open-close lid framework 31 is made of the front side parallel rod 71 that is formed with header board 31a.
About front side parallel rod 71 the bottom respectively by the bottom parts 10a of printer frame 10 supporting for be to rotate freely before and after the center with the trunnion axis 73 (main body side axis 8) that extends on the printer width, about rear side parallel rod 72 also by bottom parts 10a supporting for the trunnion axis 74 that extends on the printer width be the rotation of front and back, center freely.The upper end of front side parallel rod 71 is that connection is freely rotated at the center with respect to the leading section of pressing plate framework 18 with the trunnion axis 75 that extends on the printer width.The upper end of rear side parallel rod 72 is that connection is freely rotated at the center with respect to the rearward end of pressing plate framework 18 with the trunnion axis 76 that extends on the printer width.
Leading section at pressing plate framework 18 is fixed with row's paper guide 5 (mobile members).Under the state of having closed open-close lid 3, the part of the front of row's paper guide 5 is forwards more outstanding than the open-close lid framework 31 of open-close lid 3, and its spigot surface 5a becomes the state that tilts to printer the place ahead from record-paper outlet 4 downwards.
Secondly, the bottom of open-close lid housing 32 row's of being installed in paper guides 5 of open-close lid 3.That is, be equipped with along the horizontally extending trunnion axis 33 of printer width in the bottom of row's paper guide 5, the upper end 32a of open-close lid housing 32 is according to can be the state installation of center along the rotation of printer fore-and-aft direction with trunnion axis 33 (member side axis 9).
The bottom 32b of open-close lid housing 32 extends to the bottom parts 10a of printer 10, and this bottom 32b is connected via the leading section 10b of linking arm 34 with the bottom parts 10a of printer frame 10.The bottom 34a of linking arm 34 can be the side end face of the printer width of the center leading section 10b that is installed on printer frame 10 along fore-and-aft direction rotatably with the bolster 35 (first axle: with reference to Fig. 4) that extends on the printer width.The pivot that this bolster 35 is positioned at the front side parallel rod 71 of parallel linkage 7 is trunnion axis 73 the place aheads.In addition, be formed with the sliding tray 34b of the certain width and the degree of depth at its length direction of linking arm 34 upper edges.
On the other hand, in the side end face of the printer width of the bottom of open-close lid housing 32 32b, be fixed with to the outstanding sliding pin 36 of printer width.This sliding pin 36 can slide along this sliding tray 34b from the sliding tray 34b of printer width insertion linking arm 34, and can be around central axis (second axis) rotation of this sliding pin 36.
In addition, on the bolster 35 of printer frame 10 1 sides of the pivot of having stipulated linking arm 34, torsion-coil spring 37 is installed.Under the effect of this torsion-coil spring 37 (force application component), effect all the time has and the reverse active force of direction of toppling over to printer the place ahead on linking arm 34.
(action of open-close lid structure)
Be at open-close lid 3 under the state (with reference to Fig. 3) of the closing position 3A of erected state, the sliding pin 36 of open-close lid housing 32 1 sides is positioned at the lower end of the sliding tray 34b of linking arm 34.Linking arm 34 posture that maintenance is vertically holded up under the effect of exerting pressure of torsion-coil spring 37.Hold row's paper guide 5 when the front spurs in the locking of removing open-close lid 3, the open-close lid framework 31 of open-close lid 3 is that forwards topple at the center with the trunnion axis 73 of its bottom.In addition, the row's paper guide 5 of upper end that is configured in open-close lid 3 is keeping same posture forwards to move with pressing plate framework 18 under the effect of parallel linkages 7 of 4 joints.
To be the center with trunnion axis 73 forwards rotate with the front side parallel rod 71 of the parallel linkages 7 of 4 joints the open-close lid framework 31 of open-close lid 3.Relative therewith, because being installed in according to the state that can be the rotation of front and back, center with the trunnion axis 33 of row's paper guide 5 one sides, arranges on the paper guide 5 the upper end 32a of open-close lid housing 32, so forwards move with row's paper guide 5.Therefore, when opening open-close lid 3, open-close lid housing 32 moves when relatively sliding upward with respect to open-close lid framework 31.Thereupon, the sliding pin 36 that is fixed on the bottom 32b of open-close lid housing 32 slides upward along the sliding tray 34b of linking arm 34.In addition, because linking arm 34 is by torsion-coil spring 37 application of force rearward all the time, so the bottom 32b of open-close lid housing 32 keeps the state of pressing to open-close lid framework 31 1 sides all the time under the effect of linking arm 34 and torsion-coil spring 37.Thereby open-close lid housing 32 moves under the state that does not leave open-close lid framework 31, becomes the state of open position 3B shown in Figure 4.
(effect of open-close lid structure)
As previously discussed, in the open-close lid structure of this routine roller paper printer 1, the upper end 32a of open-close lid housing 32 is connected with row's paper guide 5, and it is mobile with this row's paper guide 5, so when open-close lid 3 was opened and closed, the upper end 32a of open-close lid housing 32 can not increase with the gap of the bottom of row's paper guide 5.Thereby rubbish such as dust can not invaded roller paper resettlement section from the gap.In addition, the air-flow that is produced by the fan that constitutes in not shown printer can not spill from this gap and in the printer circulation, rise thereby can suppress heat.
In addition, be one with such in the past open-close lid housing 32 with open-close lid framework 31 and be that the situation that forwards open at the center is compared with same trunnion axis 73, in this example, open-close lid housing 32 is according to being pressed on the open-close lid framework 31 from the state of keeping row's paper guide 5 suspentions that same posture forwards moves, thus the needed space of the switching of open-close lid 3 a little get final product.
Have again, in this example, utilize the parallel linkage 7 of 4 joints to make pressing plate framework 18 and row's paper guide 5 keep flat-hand position to open with open-close lid 3.Thereby, under the state of having opened open-close lid 3, peristome 2b that can spread rolls paper resettlement section 11, the replacing operation of roller paper 12 etc. becomes easy.
In addition, above-mentioned example is to have used the present invention in the roller paper printer of ink jet type, and but, the present invention also can be applied to possess the printer of the first-class other forms of printhead of temperature-sensitive.
In addition, in above-mentioned example, an end of linking arm 34 is connected in printer frame 10 1 sides, but, also can be connected in open-close lid framework 31 1 sides.
Have again, in above-mentioned example, linking arm 34 is rotatably mounted in printer frame 10 1 sides, in open-close lid housing 32 1 sides sliding pin 36 is installed, but, also sliding pin 36 can be installed in printer frame 10 or open-close lid framework 31 1 sides, linking arm 34 is installed in open-close lid housing 32 1 sides.
Have again, adopted torsion-coil spring 37, but, can certainly adopt force application component in addition as the force application component of open-close lid housing 32 being pressed to open-close lid framework 31.
